Femoral orthopedic implant of a knee prosthesis

Abstract

The present disclosure discloses a femoral orthopedic implant ( 8 ) of a knee prosthesis ( 100 ). The femoral orthopedic implant ( 8 ) includes a condylar member ( 12 ) and a posterior flange ( 2 ) defined by a predetermined length extending away from one end of the condylar member ( 12 ). Further, the femoral orthopedic implant ( 8 ) includes an anterior flange ( 1 ) extending from another end, opposite and away from the one end of the condylar member ( 12 ), where the anterior flange ( 1 ) is defined with a length ranging from about 0.75 to 1.4 times the predetermined length of the posterior flange ( 2 ).

1 . A femoral orthopedic implant of a knee prosthesis, the femoral orthopedic implant comprising:
 a condylar member;   a posterior flange extending away from one end of the condylar member and defined by a predetermined length; and   an anterior flange extending from another end, opposite and away from the one end of the condylar member, wherein the anterior flange is defined with a length ranging from about 0.75 to 1.4 times the predetermined length of the posterior flange.   
     
     
         2 . The femoral orthopedic implant as claimed in  claim 1 , wherein the length of the anterior flange is equal to the predetermined length of the posterior flange. 
     
     
         3 . The femoral orthopedic implant as claimed in  claim 1 , comprises a groove extending along a length of the condylar member and the anterior flange. 
     
     
         4 . The femoral orthopedic implant as claimed in  claim 1 , wherein the posterior flange is defined with a pair of posterior flange attachment members extending parallel to each other from the condylar member. 
     
     
         5 . The femoral orthopedic implant as claimed in  claim 1 , wherein the condylar member, the posterior flange and the anterior flange are integrally formed as a unitary structure. 
     
     
         6 . The femoral orthopedic implant as claimed in  claim 1 , wherein the anterior flange and the posterior flange extend integrally from the condylar member defining a C-shaped or an U-shaped femoral orthopedic implant. 
     
     
         7 . The femoral orthopedic implant as claimed in  claim 1 , wherein the condylar member, the posterior flange and the anterior flange comprises a first surface defined with a plurality of chamfers corresponding to a profile of the femur. 
     
     
         8 . The femoral orthopedic implant as claimed in  claim 1 , comprises at least one projection configured to secure and lock the end of the femur and the femoral orthopedic implant. 
     
     
         9 . A knee prosthesis, comprising:
 a tibia orthopedic implant connectable to a top end of a tibia;   an insert connectable to the tibia orthopedic implant;   a patella orthopedic implant connectable to a patella; and   a femoral orthopedic implant, connectable to an end of a femur, the femoral orthopedic implant comprising:
 a condylar member; 
 a posterior flange extending away from one end of the condylar member and defined by a predetermined length; and 
 an anterior flange extending from another end, opposite and away from the one end of the condylar member, wherein the anterior flange is defined with a length ranging from about 0.75 to 1.4 times the predetermined length of the posterior flange. 
   
     
     
         10 . The knee prosthesis as claimed in  claim 10 , wherein the length of the anterior flange is equal to the predetermined length of the posterior flange. 
     
     
         11 . The knee prosthesis as claimed in  claim 10 , wherein the condylar member, the posterior flange and the anterior flange are joined to form a unitary structure. 
     
     
         12 . The knee prosthesis as claimed in  claim 10 , wherein the anterior flange and the posterior flange extend integrally from the condylar member defining a C-shaped or an U-shaped femoral orthopedic implant. 
     
     
         13 . The knee prosthesis as claimed in  claim 10 , wherein the condylar member, the posterior flange and the anterior flange comprises a first surface defined with a plurality of chamfers corresponding to a profile of the femur.
